J'rvvmd'oa. fa ow'n/ V. 06127218072/ WILLIAM V. ROBINSON, OF OWOSSO, MICHIGAN.
OVEN-THERMOMETER.
Specification of Letters Patent.
Patented Aug. 5,1913.
Application filed October 21, 1909. Serial No. 523,854.
To all 'mh-0m z' may Gomera Be it known that I, WILLIAM V. RoBlN- soN, a citizen of the United States of America, residing at Owosso, in the county of Shiawassee and State of Michigan, have invented certain new and useful Improvements in Oven-Thermometers, of which the following is a specification, reference being had therein to the accompanying drawings.
The invention relates to thermometers, or heat-indicating devices, and it is the object of the invention to obtain a construction particularly adapted for applying to an oven.
To this end, the invention consists in the construction as hereinafter set forth.
In the drawings-Figure 1 is a front elevation of the thermometer, as applied to an oven door; Fig. 2 is a Vertical cross section through a portion of an oven door to which niy inventon is applied. Fig. 3 is a perspective View of the parts detached.
A and B are twosections of a hollow casing, preferably of circular form, and preferably secured to the oven door. The front section A is provided with a segmental depression, or recess, C, having a slot D therein through which an index E projects. This index is pivotally secured at F within the casing at a point approximately the center of the segment O.
G is a thermostatic segmental bar secured at one end to the periphery of the casing A and connected at its other end by the link H with the index E eccentric to its pivot.
The sections A and B are secured to each other preferably by bolts I, and the whole is secured in position in the oven door preferably by engaging-lugs J on the front of Gopies of this patent may be obtained for the door and by engaging the marginal portion of the circular opening therein, while the back or lining K of the `door bears against the rear face of the cas'ing.
In operation, the index E is normally held at one end of the segmental recess O, but upon a rise in temperature the thermostatic bar G will be d-e'fiected, causing the movement of the index toward the opposite` end of the recess. In this movement, the position of the index is indicated upon a scale formed in the recess C, and, if desired, numerals L may be arranged upon the face of the' casing. The rear wall of the casing B is preferably provided with a series of apertures M, permitting the heated air of the oven access to the space within the casing.
What I claini as my invention is:
The combination with an oven door having an apertured front plate and a rear or lining plate, said front plate being provided with a bearing arranged about said aperture, of a casing positioned between said plates and engaging said bearing about the marginal portion of the aperture, a therrnometer within the casing, and an index operated by the thermonieter visible from without the casing, said lining plate serving as a means for holding the casing within the bearing portion and the lining and the rear wall of the casing being provided with registering apertures.
In testimony whereof I aifix my signature in presence of two witnesses.
